FASTENING-CLASP 1 R JEWELRY.

Specification of Letters Patent.

Application filed November 16, 1920. Serial No. 424,489. V

, To all whom it mag concern:

Be it known that I, EDWARD W. Pn'rnR- SON, a citizen of the United States, residin at St. Paul, in the county of Ramsey an State of Minnesota, have invented a new and useful Fastening- Clasp for Jewelry, of which the following is a specification.

My invention relates to means for fastening Wristwatches to their bands, or the end of any watch chain to a watch or securing together the ends of necklaces or other similar jewelry, all in easily detachable manner, even if the attached parts are under considerable strain. 7 e

This object I attain by the novel construction and arrangement of parts illustrated in the accompanying drawing, in which Figure 1 is a top view mainly of my improved clasp or attaching member.

Fig. 2 is a side viewof Fig. 1 with the main lever shown in two positions.

Fig. 3 is an edge view of a wrist Watch and band attached with one of its ends to it by my improved clasp.

Referring to the drawing by reference numerals, 4 designates a wrist watch having attached to it the ends of wrist band 5 of any suitable construction. One end of the band is either permanently ordetachably secured to the eyelet 6 of the watch by a clasp 7, which may or may not be like my improved clasp which holds the other end of the band detachably to the eyelet 8 of the watch.

Said improved clasp comprisesan elongated body 9 pivoted at 10 to the adjacent end of the chain. Said body has its other end formed with a broad hook 11, which to-'.

gether with the greater portion of the body is bifurcated or formed with a groove 12 in which is fitted and normally almost con-. cealed, a lever 13 having ahook 13 pivoted at 14 between the two members of the hook 11, with which its curved form coincides when the lever is in the full line normal position shown in Figs. 1, 2 and 3.

The ring or eyelet 8 of the watch is retained in said three-membered hook by two spring arms 16 fixed on the body piece 9 and almost touching the ends of the hook members.

When the eyelet 8 is .to be disengaged from the hook members the lever 13, which is serrated at 17 for a finger nailto get easier hold of it, is swung upward and toward the face of the watch until its hook portion 13% carries the eyelet 8 to the position 8 and then to position 8 thus ejecting the eyelet from all the hook members and releasingthe watch from the band. To replace the watch, the eyelet 8 is simply hooked upon the hook members 11 and 13*, the springs 16 yielding to let the eyelet pass downward, the same as they yielded up- 1wardly during the ejection of the eyelet or oop What I claim is:

1. The combination with a wrist watch and its wrist band, of means for detachably securing said two parts together, said means comprising a wire loop or similar contrivance fixed on one of the parts, an elongated Patented Jul 5, 1921. v

body pivotally attached to the other part i and having at one end a bifurcated hook I adapted to engage in the wire loop and two the two springs, a lever normally resting in said groove .and having a hook coinciding with and pivoted between the members of the bifurcated hook close to the points thereof so as to enableit to eject the wire loop from all the hook members by a swinging movement of the lever.

2. In watch chains, bracelets, necklaces or other jewelry, a device for detachably fastening together two parts thereof, said device comprising a loop-shaped member fixed on one of the parts, an elongated body'pivotally attached to the other part and having at oneiend a bifurcated hook adapted to engage in the wire loop and two spaced spring arms on the body arranged to close with their ends the opening of the hook, said body having a groove between the two springs, a lever normally. resting in said groove and having a hook coinciding with and pivoted between the members of the bifurcated hook close to'the points thereof so as to enable it to eject the wire loop from all the hook members by a swinging movement of the lever.
